sb/intel/bd82x6x: Add and use more RCBA defines 

Taken from
"Intel 6 Series Chipset and Intel C200 Series Chipset"
Document Number: 324645-006 and
"Intel 5 Series Chipset and Intel 3400 Series Chipset"
Document Number: 322169-004 and
"Intel 6 Series Chipset"
Document Number: 324645-001.

UPDCR was found in GNU/Linux's drivers/pci/quirks.c.
DMC2 was guessed as it's close to DMC and defined for 5 series chipset.

Test:
Run BUILD_TIMELESS=1 and compared the coreboot.roms, no differences.
